Reefal habitats were sampled along two transects off the southwest coast of Puerto Rico at La Parguera Rubble (42) and sediment ( 39) samples were collected from twelve stations to ascertain their total and living foraminiferal assemblages S e diment grain size and total organic carbon (TOC) determinations were also made Cluster analysis was used to di s tinguish significant patterns of species occurrences at the stations A total of 40,443 foraminifera were collected : 23,505 from the rubble samples and 16 ,938 from the sediment samples Rubble samples contained 3,547 15% ) living specimens while the sediment samples yielded 440 (2 6 % ) living individuals. The foraminiferal assemblage off La Parguera was highly diverse and similar to other areas in the Caribbean The inshore seagrass station was dominated by Strebloides advenu s elphidiids, and bolivinids, all organophilic species indicative of calmer, backreef areas. The protected inner shelf yielded high proportions of smaller, thin-walled miliolines. The middle shelf included a variety of larger more robust species particularly members of the Superfamily Soritacea able to survive the increased energy of this envirorunent. Foraminifera at the shelf edge were dominated by Amphistegina gibbosa representative of oligotrophic habitats Rubble samples supported an appreciable living population compared to the s ediment samples Grain sizes and sediment TOC levels corresponded to the areas of the shelf sampled Regions dominated by smaller grain sizes had highe r TOC values and contained viii

higher numbers of smaller, fragile miliolines. Conversely, regions with higher proportions of larger grain sizes typically had lower TOC values and contained larger percentages of larger thicker foraminifera Abstract Approved: Major Professor : Pamela Hallock Muller, Ph.D. Professor, Department of Marine Science Date Approved : IX

1 INTRODUCTION Interest in foraminifera began around 1920, when they were used in the search for petroleum. In the years following, study of both fossil and modern assemblages intensified. Ecological, taxonomic, and sedimentologic studies of foraminifera have been undertaken by numerous researchers in a variety of regions throughout the Caribbean. Cushman's studies (1922b 1923, 1929, 1930, 1931b) of the distribution of foraminifera in the Atlantic Ocean are regarded as benchmark publications Interest in carbonate systems as hydrocarbon reservoirs increased around 1950, stimulating studies of benthic foraminifera as important constituents of shallow-water calcareous sediments (Illing, 1952; Todd and Bronnimann, 1957; Bandy, 1964; Cebulski, 1969; Todd and Low 1981) More recently, relationships among environmental parameters and specific foraminiferal assemblages have been stud i ed to determine the ecological niches of these microorganisms (Sen Gupta and Schafer 1973; Brasier, 1975a; Steinker and Steinker, 1976). Tropical environments off Puerto Rico's coast support diverse populations of foraminifera. The composition and distribution of these distinct foraminiferal assemblages have been studied by several researchers. Flint (1900) identified and recorded foraminifera collected in dredges at seven stations on the Fish Hawk expedition. Cushman (1926) expanded on Flint's work to better understand

2 sedimentation in the West Indian region and increase the knowledge about the endemic foraminiferal fauna Seiglie (1971a) studied the distribution of foraminifera on the Cabo Rojo platform and in Mayagiiez and Afiasco Bays (Seiglie, 1971b, 1974) on the west coast of the island, and in Yabucoa Bay (Seiglie 1970a) on the southeastern portion of the island. Brooks (1973) examined distributions of Recent foraminifera from 36 samples along three transects off the central south coast using quantitative cluster analysis to determine trends in assemblages in this region. Saunders and Schneidermann (1973) examined carbonate sediment samples from 54 shallow-water stations from Cayo Enrique, located off the southwest coast, using grain-size analysis, carbonate mineralogy, and in situ examinations of the environmental setting to produce a descriptive model of sedimentation on the inner shelf of area More recently, Culver (1990) characterized benthic foraminifera in two mangrove-lagoon habitats off the south coast. Background The Caribbean waters off the southwest coast of Puerto Rico were described as moderately oligotrophic by Hallock (1988a). They were designated as such because the euphotic zone, the depth to which the 1% light level penetrates the surface, is between 75 and 100 m. The offshore reefs within these waters are dominated by scleractinian corals and calcareous algae Field work in this area in the early 1980s revealed that the larger symbiont-bearing rotaliid foraminifer Amphistegina gibbosa,

PAGE 16

3 indicative of oligotrophic conditions was prolific (Hallock, pers comm.). Moving inshore from the shelf edge across the intermediate and inner lines of reefs, there was a noticeable shift from a coral-algal dominated substrate to an environment with fewer hermatypic corals, and a greater abundance of gorgonians, sponges, and fleshy, non calcareous algae. Strings of fine-grained sediments within an organic gel matrix often draped the hard substrate of the inner and intermediate arc of reefs where particulate matter was evident in the overlying water column (Hallock, pers comm.) It is well-documented that tropical reef formation reef growth, and species diveristy within reef habitats is influenced by fluctuations in nutrient availability (e.g., Birkeland, 1977; Hallock and Schlager, 1986 ; Hallock, 1988a, 1988b). Truly oligotrophic environments, such as the waters surrounding Pacific atolls, are characterized by lush coral or coral-coralline algal development Slight increases in nutrients result in a community co-dominated by coral and algae but with a preponderance of a variety of non hermatypic populations (e.g benthic algae sponges, gorgonians, and mollusks) (Wilkinson, 1986; Birkeland, 1987 1988) Many offshore areas of the Caribbean fall within this category. Still higher nutrient levels, as are found in non-reefal areas of the Florida Keys, can inhibit coral growth and lead to the proliferation of a sponge-algal dominated community. Additions of nutrients to oligotrophic habitats can stimulate bacterial growth, phytoplankton blooms or both, that affect coral growth by (1) decreasing w ater transparency and concomitantly reducing the amount of light reaching the reef ultimately inhibiting the growth of the zooxanthellate coral; (2) increasin g the amount of organic material available to faster growing suspension and filter feeders that out

PAGE 17

compete corals, shifting the composition of the community; and, (3) increasing the occurrence of bioeroding organisms weakening the reefal framework making it more susceptible to destructive forces (Risk and MacGeachy, 1978; Highsmith, 1980). 4 The primary question behind this thesis project was "Do the benthic foraminiferal assemblages reflect the visible biotic and sedimentologic differences between the inner and outer reefs at La Parguera, and if so, how?" Additionally, living benthic foraminiferal populations (biocoenoses) indicate conditions at the time and place of sampling, while total (living plus dead) assemblages reflect conditions over some interval of time and space. Rubble was sampled to acquire information on the living populations because many shallow-water benthic foraminifera live on solid or vegetated substratum. The sediments were sampled to represent the temporally and spatially integrated assemblages The objectives of this study were threefold : (1) to characterize the benthic foraminiferal assemblages along two inner reef to outer-reef to shelf-edge transects off the southwest coast of Puerto Rico to determine trends in species comp os ition and diversity within two habitats, rubble and sediment, (2) to compare living and total (living plus dead) populations both in rubble and sediment samples, and (3) to examine species assemblages in relation to environmental parameters, particularly grain size and organic carbon content of the sediments. Site Characterization La Parguera is a small town on the southwest coast of Puerto Rico (F i g ure 1),

7 the smallest and easternmost island of the Greater Antilles in the western Caribbean Sea Situated on the leeward edge of the Cordilleran Central mountain range with an annual rainfall of 75 em, an annual evaporation rate of 203 em and a mean annual temperature range of 21 26 C La Parguera's climate is classified as semi-arid (Coker and Gonzales 1960 ; Almy and Carri6n-Torres, 1963; Saunders and Schneidermann 1973 ; Schneidermann et al., 1976 ). Interannually, variable wet and dry s easons extend from appro x imately May to November and from December through April, respectively ( Glynn, 1973 ). The amount of annual rainfall in La Parguera cannot sustain a permanent river Consequentl y sediment discharge from the mountains is typically low or non-existent. During heavy rains however runo f f is often significant and appreciable discharge may occur at these times (Saunders and Schneidermann, 1973 ; Coker a nd Gonzalez, 1960) The trade winds dominate throughout most of the year establishing southeasterly or east-southeasterly winds of 15 20 knots (Kimmel 1985) The coastal waters off La Parguera are dominated by the Antilles Current, a part of the North Equatorial Current which influences the entire Antilles archipelago (Kaye 1959; Brooks, 1973). Oceanic surface currents flow parallel to the coast in a westward direction at an a verage rate o f 7 -13 em / sec Entrained coastal currents also flow westward and follow the convoluted shoreline ( Kaye 1959; Glynn, 1968). The numerous patch reef s and s hoals in the area create an irregular bottom topograph y w h i ch acts to decrease the effect of currents and waves on the shore (Brooks 1973) Tides at La Parguera are diurnal and variable with a range of less than 0.5 m Consequently, tidal currents are relatively weak

PAGE 21

compared to surface currents (Kaye, 1959; Glynn, 1973; Saunders and Schneidermann, 1973). 8 Mean surface water temperatures range from 25 to 32 C (Kaye, 1959; Almy and Carri6n-Torres, 1963; Glynn, 1973; Saunders and Schneidermann, 1973; Culver, 1990) and mean surface salinities vary from 33 to 37o/oo (Glynn, 1973; Saunders and Schneidermann, 1973; Culver, 1990) Variability in temperature and salinity is higher in the more protected, shallower water of backreef areas due to increased daily temperature fluctuations, radiation from the bottom, and wind intensity. Daily temperature differences in a backreef lagoon can range from 10 to 12 C (Almy and Carri6n-Torres, 1963; Glynn, 1973). Glynn (1973) reported that the bathymetry of the southwest coast of Puerto Rico is a consequence of the deformation of Upper Cretaceous limestone, interbedded with volcanic rocks and mudstones, into a WNW ESE syncline that runs through Isla Magueyes. The contours of the relatively wide insular shelf, exposed to subaerial processes in the Wisconsin glacial epoch (Morelock et al., 1977), are a result of the structure of either underlying basement rock or the position of sand dunes along the relict shoreline ( Almy and CarrionTorres, 1963). Modest annual riverine sediment input, low rainfall, the influence of oceanic currents in relatively sheltered waters, and antecedent topographic relief account for the offshore reef development of the area (Almy and Carri6n-Torres, 1963; Wells, 1988). Two arcuate reef systems parallel the coast and separate the shelf into three distinct reef-dominated regions (Figure 1) with characteristic bottom morphologies

9 and sedimentary regimes thought to be influenced by local wave energy (Morelock et al., 1977). The outer shelf province, situated 2 -3 km offshore is bounded by the shelf edge and forereef of the outer arc of reefs. Gravelly sand dominates and is comprised mainly of skeletal debris: Halimeda plates, benthic foraminifera, mollusk shells and coral pieces. Very little fine sediment is found within this region (Morelock et al., 1977). A mid-shelf expanse lies between the forereefs of the inner arc of reefs to the backreefs of the outer arc of reefs This region is further subdivided into a backreef lagoon, reef apron (backreet) and forereef, each with a characteristic sedimentology. Fine-grained sandy silt consisting of 30 40% shell pieces are the major components of the lagoonal sediments. Other major constituents include coral fragments foraminifera, and Halimeda (Morelock et al 1977) Mollusk and coral debris and Halimeda plates comprise the sands of the backreef and forereef regions where there is an increased contribution from coralline algae The inner arc of reefs lies approximately 1 km offshore creating an inner shelf extending from their backreefs to the shoreline. This area is dominated by numerous patch reefs in varying developmental stages (Almy and Carri6n-Torres, 1963; Glynn 1968) The subprovinces of the inner shelf are more complex encompassing four environments: a mangrove-dominated coast Thalassia and Halimeda beds, Ahogada reef, and a backreef lagoon (Almy and Carri6n Torres, 1963 ; Morelock et al., 1977) Both the shallows adjacent to the mangrove-dominated coast and the offshore stands of Thalassia and Halimeda are dominated by carbonate silts and sands. Encrusting foraminifera mollusk, and coralline algae detritus are also important sedimentary

PAGE 23

10 contributors. Ahogada Reef is a strip of disconnected patch reefs midway between the shore and the inner reef line. The sediments on both sides of this reef are moderately-sorted, fine sands and silts consisting primarily of coral fragments and Halimeda plates (Saunders and Schneidermann, 1973; Morelock et al., 1977). A variety of constituents including mollusk and echinoderm pieces, coralline algae, and foraminifera make up less than 20% of the sand fraction. The backreef lagoon between the backreef of the inner reef line and Ahogada Reef is dotted with intermittent patch reefs and covered by fine-grained muds of Halimeda chips, green algal needles, foraminiferal and coral fragments, and coccoliths. A thin, mucousy layer of fllamentous algae partially stabilizes the bottom silts and clays (Morelock et al., 1977). METHODS Field sampling was performed in May 1985 A total of 105 samples were collected at twelve sites ranging from 0.1 to 9 km off La Parguera (Figure 1). Fewer sites were sampled in the middle shelf region and at the shelf edge because of the logistics involved in accessing these outlying areas Samples were obtained by SCUBA divers along two transects encompassing a variety of habitats including seagrass beds, patch reefs, and an offshore spur and groove system (see Appendix 1). Transect I comprised, proceeding from inshore to offshore, Stations G, D, C, J, B A, and M. Transect II included Stations 0, I, F, E, H, and M. Station M was

PAGE 24

11 included in both transects as an anchor point because it was the only station at the shelf edge Four types of samples were acquired at each station : (1) reef rubble samples comprised of dead coral pieces, molluscan fragments, and coralline algal nodules for foraminiferal analyses; (2) surface (upper 1 2 em) sediment samples of approximately 45 cm3 collected in the vicinity of the rubble samples at that depth, to determine the foraminiferal assemblages; (3) one 31h" sediment core, subsampled from the top and bottom, to measure organic carbon content; and, ( 4) one sediment sample of approximately 177 cm3 of which approximately 10 -14 g was subsampled, for grain-size analysis. Seven of the 12 grain-size samples were analyzed One sample per reef was selected for analysis with the exception of Stations G and H which were not processed. Whenever possible, both sediment and rubble samples for faunal analyses were obtained from multiple depths at each site to adequately represent forereef, reef platform, and backreef environments. Standard physical and chemical parameters measured whenever possible at each station were surface (2 m) water temperature, salinity and dissolved oxygen and meteorological data (see Appendix 1). Depth to anoxia in the substrate was approximated at each station by estimating the depth at which the sediment color exhibited a noticeable change from cream or tan to dark gray. Photographs were taken to qualitatively describe the habitats of each environment sampled. Sample Processing Rubble and sediment samples collected for foraminiferal abundance

PAGE 25

12 determinations were fixed (quick-killed) and stained overnight using Rose Bengal dissolved in 0.2% buffered formalin to distinguish individuals alive at the time of collection (Walton, 1952) (see Figure 2). These faunal samples were then washed over a 63 p.m mesh sieve to remove excess preservative, and air-dried. The sediment samples for grain-size analysis were air-dried for transport. Grain size distributions and sediment constituents were determined as outlined in Milliman (1974). Sediment samples for organic carbon measurements were frozen until laboratory analysis. The persulfate-ampoule method of oxidation (Menzel and Vaccaro, 1964; Williams, 1969) was used in the total organic carbon analyses. Each faunal sample was re-washed in the laboratory to remove fine silt and clay particles and oven-dried overnight at 45 -so c. Rubble Samples Rubble pieces were brushed clean of debris including sediment algal fragments, and foraminiferal tests, over a 2 mm sieve Clumped material was disaggregated and examined for loosely attached foraminifera, which were dislodged and placed in the < 2 mm (fine) fraction Foraminifera were picked from the > 2 mm fraction and added to the fine fraction. The fine fraction was floated in trichloroethylene (C2HC13 ) to separate and concentrate the mostly hollow foraminifera from heavier constituents (Gibson and Walker, 1967). Both "light" and "heavy" fractions were examined. The light fraction contained the majority of foraminifera tests, but the heavy fraction often included many of the thicker-walled, more robust species. Both fractions from each

14 rubble sample were split to a total sample size of approximately 300 individuals using a microsplitter mounted on a shaker. This is standard procedure in foraminiferal assemblage determinations (e.g., Murray, 1973). Foraminifera were picked, mounted on micropaleontological slides, categorized as alive or dead at time of collection identified to lowest taxon possible, and counted. The perimeter of each rubble piece was traced using a Southern Micro Instruments MicroComp Integrated Image Analysis System equipped with a 24 nun camera lens. This provided a measurement of the projected planar area of each rubble piece, which in tum produced an estimate of the abundance of foraminifera per unit area of habitat. The average of three measurements was calculated for each sample. Sediment Samples Each sediment sample was dry-sieved over a 2 mm mesh screen prior to processing Successive scoops of sediment were picked until approximately 300 foraminifera were obtained. Each individual was mounted on micropaleontological slides, identified to lowest taxon possible, classified as alive or dead at time of collection, and enumerated. Samples were weighed to the nearest 0 .01 g using an electronic balance after the foraminifera were picked Foraminiferal test weights were negligible when compared to those of the subsamples. Weights (sediments) and surface area (rubble) were measured to standardize foraminiferal counts and prevent bias due to dissimilar sample size.

PAGE 28

15 Scanning electron micrographs were taken of specimens classified as abundant, taxa present in greater than 75% of samples in both sediment and rubble habitats (see Appendix 2). Statistical Analysis Density (absolute abundance) the number of foraminifera per cm2 rubble or number of foraminifera per gm sediment was calculated from foraminiferal counts and standardized to the entire sample Relative abundances were computed by dividing the number of individuals in each taxa by the total number of foraminifera in each sample. Diversity of both rubble and sediment samples was calculated using the Shannon Wiener coefficient (H1 Shannon and Weaver, 1949) : where: s HI = E Pi ln (p) i=l S number of species p = proportion that each species i represents within each sample Evenness (V, Pielou, 1977), also referred to as relative diversity or homogeneity, was determined for each sample using the formula: where: V = H11log S* H 1 = ShannonWiener Index S* = total number of species in the community (S* in these analyses was the total number of species in each sample )

PAGE 29

16 Both absolute and relative abundances of the rubble and sediment total assemblages, and the living rubble assemblage were utilized in the multivariate analyses Samples were treated as single replicates and were also grouped by station All data were nontransformed, log [(In (x + 1)] transformed, and binary transformed (presence absence) for use in the cluster analysis (McKenna, pers. comm.) Agglomerative, hierarchical cluster analyses were run using the Bray Curtis resemblance measure (Bray and Curtis, 1957) and the unweighted pair-group method utilizing arithmetic averages (UPGMA) (Sneath and Sakal 1973 ; Clifford and Stephenson, 1975) Dendrograms were generated from the results. A bootstrapping procedure resampled the abundance data to calculate standard error estimates and determine the significance of the linkages of the clusters generated (Nemec and Brinkhurst, 1988). Unless otherwise stated significance was considered to be at P =::; 0.05. With the exception of diversity and evenness computations, statistical tests were run using two groupings of the data. The first encompassed all species found in the entire assemblages. The second excluded species that occurred in fewer than three samples or had fewer than six individuals in a single sample, in both rubble and sediment collections. RESULTS Overall Foraminiferal Assemblage Composition A total of 40 443 individual foraminifera from 231 taxa were identif i ed (see

Forty-two rubble samples contained 211 taxa and 215 taxa were found in 39 sediment samples with 195 taxa common to both habitats (Table 1) Table 1 Summary statistics of rubble and sediment samples Rubble 42 samples 23,505 specimens 211 taxa 79 genera 3,547 live specimens 124 live taxa Sediment 39 samples 16,938 specimens 215 taxa 82 genera 440 live specimens 80 live taxa Numerically, the 25 most abundant taxa accounted for 64% of the entire rubble assemblage (Table 2). Of these 25 taxa, 14 were miliolines including 6 species of Quinqueloculina; 11 were rotaliines (Spirillina vivipara is included in this category) Rosalina was the most prolific rotaliine genus contributing 14% to the entire population. Similarly, 62% of the foraminifera in the sediment assemblage was comprised of the 25 most abundant taxa (Table 2). Amphistegina gibbosa was the single most abundant species, accounting for 6 8% of the sediment-based foraminiferal population. Two Rosalina taxa accounted for approximately 5% of the assemblage. The most common of the milioline taxa was Quinqueloculina s ignata, which contributed 4 .8% to the sediment assemblage Quinqueloculina was the most speciose and most abundant porcellaneous genus in both rubble and sediment

19 populations, with a total of 40 species. Rosa/ina and Amphistegina were the two most abundant hyaline genera in both rubble and sediment samples. Rubble Textulariines accounted for up to 7% of the total in each rubble sample, with most containing between 0 5 and 3 0% (Table 3). Porcellaneous and hyaline (calcareous perforate, including representative from the suborders Spirillinina, Lagenina, and Globigerinina) taxa each consistently represented 40 to 60% of rubble samples The highest percentage (70) of porcellaneous taxa occurred in sample PR-74 at Station D while hyaline taxa constituted 80% of sample PR-85 at Station G. Samples collected at Stations C, D, and 0 consistently contained 55 70% porcellaneous taxa while samples from Station M contained between 65 and 75% hyaline taxa Sediment Textulariines contributed slightly higher percentages in some of the sediment samples, the highest contribution was 12% in sample PR-41 at Station E (Table 4) As in rubble samples, however, most sediment samples contained 0 5 3 0% textulariines Unlike the rubble samples in which neither porcellaneous nor hyaline taxa clearly dominated, porcellaneous taxa contributed greater than 50% of the total

24 in 32 of 39 sediment samples. Again, all samples from Stations C, D and 0 were composed of > 55% porcellaneous taxa, the highest percentage (72) was obtained in sample PR-76 at Station D The highest proportions of hyaline taxa were again found in both samples from Station M accounting for approximately 65 70% of individual sample assemblages. The contribution of planktonic taxa, included in the hyaline taxa, was most noticeable in both rubble and sediment samples from Stations M where percentages ranged from approximately 3 to 13. Foraminiferal Assemblages of Rubble Samples Total Assemblages Generally, thinner-walled miliolines were found in greater relative abundances in samp l es closer to shore and at the s helf edge, particularly at Stations G, 0 C, a nd D Often associated wi th these samp le s were sediments with higher organic carbon content and smaller grain size in areas with diminished wave action. In stations proceeding offshore, the foraminiferal fauna was dominated by porcellaneous (milioline) and hyaline (rotaliine) taxa when compared to textulariine taxa. Textulariines were collected, but were not found in the abundances of the other two major suborders. Taxa from the s ub orders Spirillinina, Lagenina, and Globigerinina were included in the hyaline category in the analyses, unless otherwise specified Data for individual rubble samples are presented in Table 5 in Appendix 4

25 Station G (inshore of the inner reef line), was dominated by Strebloides advenus (30%) followed by Bolivina striatula ( 11 %) and Cribroelphidium poeyanum (9%) (Figure 3). Of the few notable miliolines, Quinqueloculina sabulosa and Q. bosciana each contributed approximately 3% to individual sample assemblages. No textulariines were collected at Station G. Miliolines and encrusting rotaliines were the main taxa from samples coll e cted at Station D (backreef of Cayo Enrique) Prominent porcellaneous taxa included Q. seminulum, Q signata, Miliolinella cir c ularis, Triloculina bennude z i, and T. oblonga. Each consistently contributed 1.5% to i ndiv i dual samples Strebloides advenus, Rosa/ina globularis R spp., and Amphiste g ina gibbosa were the most abundant rotaliines accounting for 1% of each sample (Figure 4). Samples from Station C (forereef of Cayo Enrique), contained significant proportions of Q polygona Q. seminulum, Q signata, M. circularis, T bennudezi T. trigonula, and Sigmoilina bradyi These s ix species accounted for approximately 25 31% of each sample. The most abundant hyaline taxa included Rosa/ina globularis, R spp and A. gibbosa, totaling between 10 and 19% (Figure 5) Quinqueloculina signata and M circularis each accounted for 2.5 10 % of samples from Station J (Laurel Reef) Although not as consistent in their abundances among samples Cyclogyra planorbis Q seminulum T bennude z i, Arti c ulina pacifica and Pener o plis protea contributed significantly to the milioline fauna Combined Discorbis rosea R. globularis R spp and Planorbulina mediterranensis accounted for between 19 and 32 % of each individual s ample (Figure 6)

34 Miliolines and encrusting rotaliines dominated samples from Station B (backreef of Media Luna). Cyclogyra planorbis, Q seminulum Q signata M circularis and T bermudezi predominated, each contributing > 2.5% to each sample. Rosalina globularis, R spp., and P mediterranensis consistently accounted for 2 10% of individual samples Discorbis rose a contributed 2 4%, twice as much as in forereef samples (Station A). Amphistegina gibbosa accounted for < 1% of each sample (Figure 7) Thicker-walled miliolines such as Articulina pacifica Peneroplis protea, and Archaias angulatus were collected in significant proportions combining for between 3 and 8% of samples from Station A (forereef of Media Luna) Thinner-walled forms remained abundant. Rosalina globularis, R. spp. A gibbosa, and Planorbulina mediterranensis were the major hyaline taxa represented, together contributing 16 to 26% to each sample (Figure 8). The most abundant miliolines at Station M (shelf edge), were Q. signata, M circularis, and T bermudezi, accounting for approximately 1 4% of samples Hyaline forms were dominated by A gibbosa which constituted over 15% of each sample.

Strebloides advenus, R globularis, and A. gibbosa were the most plentiful hyaline forms, combining to add approximately 12 16% (Figure 10) 41 Porcellaneous taxa such as C. planorbis, Q signata M circularis T. bermudezi, and Peneroplis protea contributed between 22 and 26% to the foraminiferal fauna in samples from Station I (Arrecife Enmedio) Encrusting R. globularis, R. spp and Planorbulina mediterranensis were the most common hyaline taxa, adding approximately 15 to 24% to each sample (Figure 11). The milioline taxa in samples from Station F (backreef of Turrumote), was dominated by Q seminulum Q signata, M circularis and T. bermudezi These four species accounted for approximately 15 33% of each assemblage. Discorbis rosea, R globularis, and R. spp. together contributed an additional 16 to 28% to individual samples (Figure 12) Generally, abundances of most taxa in Station E (Turrumote forereef samples) were similar to Turrumote backreef samples. The proportions of some thin-walled miliolines (e.g., Miliolinella circularis) were lower than some of the more robust miliolines Q. lamarckiana, Q. polygona, Articulina pacifica and Peneroplis protea. Together, these species contributed approximately 4-11% Rosalina globularis R spp., and Amphistegina gibbosa each accounted for between 3 and 13% of individual samples (Figure 13). Textulariine species accounted for low percentages but they were consistently found in samples at Station H (south of Turrumote) Quinqueloculina signata, M. circularis and T bermudezi were the prominent milioline taxa each contribut i ng >

Rosalina g lobularis, R. spp. and A g ibbosa also each added > 3% to each assemblage (Figure 14) Biocoenoses Of the total 23,505 foraminifera in the 42 rubble samples, 3,547 individuals (15%) representing 124 taxa were alive at the time of collection (Table 6, Appendix 4). Twenty taxa (16%) accounted for approximately 73% of the living assemblage (Table 7) Miliolines were represented by eleven taxa: Cyclogyra planorbis, Quinqueloculina polygona, Q seminulum, Q signata, Miliolinella circularis, Triloculina bennudezi, T. trigonula, Sigmoihauerina bradyi, Articulina pacifica, Peneroplis protea, and Archaias angulatus. Hyaline taxa consisted of Spirillina vivipara, Bolivina subexcavata, Buliminella milletti, Trifarina occidentalis, Rosa/ina floridana, R. globularis, R spp., Planorbulina mediterranensis, and Amphistegina gibbosa. Although the number of dominant taxa from the two major groups was similar, the contributions of individual taxa at particular stations along the sampled transects were different (Table 6, Appendix 4). Very few individuals were collected alive at inshore Station G (Transect I). Milioline taxa accounted for most living individuals from samples at Station C and D (Cayo Enrique) The most notable exceptions were the (relatively) larger contributions of Rosa/ina spp., Planorbulina spp, and Amphistegina gibbosa in samples from Station C.

54 globularis, Planorbulina mediterranensis, and A. globu lari s dominated the live assemblage collected at Station J. Both living miliolines and rotaliines were collected from samples at Stations A and B ( Media Luna) in similar proportions, the major difference being a higher proportions of live R. globula ris and Amphistegina gibbosa at Station A Very few living miliolines were found in sample s from the shelf edge at Station M. Amphistegina gibbosa clearly dominated the living assemblag e Both miliolines and rotaliines were represented in the living assemb lage in nearshore Station 0 samples (Transect II), althoug h no tax on occurred consistently in large abundances. Miliolines Miliolinella circularis and Triloculina bennudezi a nd rotaliines Rosa/ina globularis and Planorbulina mediterranensis dominated the live assemblages at Station I. Samples from Stations E and F contained living representatives of miliolines and rotaliines in similar proportions with no single taxon dominating Rotaliines contributed s lightl y higher proportions than miliolines to Station H samples. Foraminiferal Assemblages of Sediment Samples Total Assemblages Miliolines were often more abundant in the sed iment samples due to the increased contribution of the heavier, more robust varieties. Data for individual sediment samples is in Table 8 in Appendix 4.

55 Nearshore Station G, Transect I, was clearly dominated by Strebloides advenus which accounted for 28 % of the assemblage. Cribroelphidium poeyanum, Bolivina striatula, Tretomphalus bulloides, and Elphidium advenum contributed an additional 16.5%. Miliolines Quinqueloculina bosciana and Triloculina trigonula together added about 11% to the sample (Figure 15). Ten miliolines from samples collected from Station D : Quinqueloculina bosciana Q poeyana, Q. polygona, Q. seminulum, Q. signata, M. circularis, Triloculina oblonga, T trigonula, Sigmoilina bradyi and Peneroplis protea, accounted for between 25 and 40% of each sample Major rotaliine taxa included Strebloides advenus, Rosalina globularis, and R. spp. Discorbis rosea was found only in PR-38, but it accounted for 14% of that sample (Figure 16) Textulariine taxa contributed from 0 5 4.5% to each sample from Station C. Miliolines Quinqueloculina seminulum, Q. signata, Miliolinella circularis, Trilocuiina oblonga, and T. trigonula accounted for 25 to 32% in each sample. Rosalina globularis and Strebloides advenus were the major hyaline taxa, combining to add 8 to 10% to each assemblage (Figure 17). Relatively robust porcellaneous species Quinqueloculina lamarckiana, Q signata, Triloculina trigonula Borelis pulchra Peneroplis protea, and Archaias angulatus constituted approximately 13 26% of each sample collected at Station 1 (Figure 18). Discorbis rosea and Amphistegina gibbosa dominated the hyaline taxa adding another 4 to 29% to each individual sample. Approximately 23 to 33% of each sample collected at Station B (Figure 19)

The three species of Peneroplis collected and Archaias angulatus combined to added approximately 6 10% to the samples. Rosalina and Amphistegina were the two most common genera, combining to add 18 to 20% to each sample (Figure 26). Biocoenoses Only 2.6% of the foraminifera from the sediment samples were alive when collected The three species with the highest number of live representatives were Tretomphalus bulloides (33), Triloculina trigonula (28), and Quinqueloculina seminulum (24) Cluster Analysis No significant groupings of the relative and absolute abundance data were found when each sample was treated as a single replicate. Consequently, it was assumed that the different depths from which samples were collected at a single site were not significantly different in species composition. Multiple samples at 11 of the 12 sites were considered as replicates (only one rubble and one sediment sample was processed from Station G).

Non-transformed data clustered into five major significant groups : the first contained Stations A, B E, F H, I, and J the second comprised Stations C and 0, and the third, fourth, and fifth consisted of single stations D, M, and G respectively (Figure 27). Similar results were obtained when 39 rare species were deleted from the database with the exception of the log-transformed data which did not generate any statistically significant groups. Three significant groups were produced when absolute abundances of the rubble samples (non-transformed data) were analyzed. Station G and Station H each clustered as an individual group and the third group comprised the rest of the stations. The same pattern was obtained when the 39 rare species were omitted. Analysis of non transformed absolute abundances of live foraminifera from all sites produced a pattern similar to that found when non-transformed relative abundances of the total rubble assemblage were used (i.e., five separate groups formed). Stations G M, and H were distinct while Station D was included with Stations 0 and C. Stations A, B, E F, I, and J constituted the fifth group (Figure 28). Three significant groups were produced when the relative abundances of sediment samples (non transformed data) were analyzed, Stations G and H, again clustered out separately from the remaining group of ten stations (Figure 29) The same result was obtained when the 39 rare species were deleted.

Medium and fine sands dominated in all samples except Stations C and 0 the most inshore stations, in which the mud fraction was most prevalent Station I was the only sample in which coarse sand (1 mm size fraction) dominated Sediments at all stations were either poorly or very poorly sorted The most abundant identified constituents in all size classes were mollusk shells (pelecypods and gastropods) benthic foraminiferal tests, and calcareous green algal fragments. Benthic foraminifera were most abundant in the 0 25 mm and 0 50 mm fractions while calcareous green algal and mollusk remnants dominated in the coarser sand fractions (1 and 2 mm) Organic Carbon The amount of organic carbon (% C dry wt) in sediments was generally higher in the tops of sampled cores than in the bottom of the cores in all samples except Station C (Table 9) Values from core tops ranged from 0 33 % C dry wt at Station M to 1.95 %C dry wt at Station G. Organic carbon content in core bottom samples ranged from 0 20 %C dry wt at Station H to 1.32 % C dry wt at Station C Although somewhat variable the prevailing trend was of increased organic carbon

93 evenness values showed a similar pattern for sediment samples The lowest diversity value (2.15) was obtained in PR-53 at Station E, while the highest value of 4 .17 was obtained from sample PR-107 at Station I (Table 11) Likewise, 28 of 39 (72%) sediment samples had diversities between 3.5 and 4.0 with corresponding evenness values of 0.65 to 0.74. DISCUSSION The reefs along both transects studied off La Parguera, Puerto Rico contain a rich assemblage of foraminiferal species. The species identified from the reefal habitats at La Parguera are consistent with those found by others studying the Caribbean/ Antillean province [e.g., the south, central coast of Puerto Rico (Brooks, 1973), the Florida Keys, (Bock, 1971; Steinker et al., 1977; Hallock et al 1986a; Martin 1986), Barbuda (Brazier 1975a, 1975b), Bahamas Bank (llling, 1950 ; Todd and Low ; 1971; Steinker and Steinker, 1976), and Jamaica (Martin and Liddell, 1988, 1989)]. The presence of such diverse assemblages in the majority of the samples from the reefs and the similarity and relative consistency of the proportions of textulariine porcellaneous, and hyaline taxa make it difficult to ascertain any significant trends. Ternary diagrams, a technique often used to categorize specific habitats by their species compositions (Murray, 1973; Brazier, 1975a, 1975b), are not entirely applicable to the present data set. Only Stations G and M contain proportions of

96 rotaliines and miliolines that are distinctly disparate enough to be depicted in a ternary diagram Steinker et al. (1977) were also unable to utilize this technique because the compositions of foraminiferal assemblages from two reefal habitats in the Florida Keys were so similar With homogenous data sets it is necessary to examine the relative contributions and distribution patterns of species groups to characterize individual sample sites Culver (1990 ) asserted that foraminiferal abundances and distributions are related to sediment substrate type presence of vegetation, and the physical energy of the environment. Brooks (1973) ascribed any difference s in species a s sembla g es to varying environmental parameters particularly circulation, currents, and the morphology of the underlying continental shelf Both Transects I and II cut across the middle and inner regions of the shelf formed by the inner and outer reef lines Each resultant province possesses unique features that account, in part for the foraminiferal assemblages found there. Inner Shelf Province The repeated separate clustering of Station G is consistent with the substrate composition at this station Although designated as rubble this s ample did not include what was typically collected as rubble (i. e., p i ece s of dead co ral mollusk shells, o r limestone rock), but rather consisted of Thalassia testudinum blades and thallus When the surface area of the rubble s amples was calculated to determine

PAGE 110

97 standardized abundances, the value for this sample was narurally very small Consequently, sample PR-85 from Station G had a very large total number of foraminifera per cm2 In addition, the sediments from this station (PR-81) contained grains which resembled "coffee grounds The dominance of Strebloides advenus and the prevalence of Bolivina striatula, Cribroelphidium poeyanum and Elphidium advenum characterize the protected, shallower environments at Station G, and to a lesser extent, Stations 0 and D in the backreef of the inner reef line. These organophilic species thrive in restricted habitats (Hallock, pers. comm.) Therefore, the prevalence of S. advenus in both the rubble and sediment samples was most likely responsible for Station G falling out as a distinct, significant assemblage. Other researchers have found these species, or closely related taxa, in shallower, more restricted habitats (Bandy, 1954; Buzas et al. 1977). In examining the benthic foraminiferal assemblages of two mangrove-lagoon environments off Puerto Rico's south coast, Culver (1990) found Ammonia tepida (Strebloides and Ammonia are both now considered members of the Family Rotaliidae) to be the dominant species both landward and seaward of the mangrove islands in two transects located 1lf2 miles east of La Parguera. Bolivina striatula and Elphidium spp. were also significant components of the population in both the inshore and offshore lagoons. Sen Gupta and Schafer (1973) also found Ammonia tepida to be an important constituent in samples from two bays of St. Lucia, particularly in the more enclosed, restricted one. Seiglie (1971a) noted the abundance of this species within the mud in the back-reef bay facies in the Cabo Rojo platform off Puerto

PAGE 111

Rico s west coast. Also prevalent were various small thin-walled miliolids and Elphidium discoidale and E. poeyanum. Cebulski (1969) found Rotalia beccarii (Rotalia is also in the Family Rotaliidae), along with Elphidium discoidale and E. poeyanum, common in lagoonal fauna in samples from British Honduras (now recognized as Belize). 98 Higher organic carbon content and a finer grain size are often associated with a more diverse, abundant smaller foraminiferal assemblage (e.g., Brasier, 1975b ; Huse, 1976; Steinker et al. 1977; Culver 1990). Smaller, thinner-shelled individuals tend to inhabit these areas taking advantage of the increased food suppl y Typically, protected envirorunents of lower wave energy allow finer-grained sediments, including thinner-w!llled, more fragile benthic foraminiferal tests, to accumulate Often associated with the finer grains is an increased amount of organic detritus which serves as a food source. Sediments at Stations C and 0 were dominated by mud-sized particles and they contained relatively higher numbers of milioline taxa. Particularly, porcellaneous taxa with more fragile tests including Quinqueloculina bosciana, Miliolinella circularis, Triloculina bermudezi and T. oblonga were abundant. Each of these occurs in relatively higher proportions in Stations 0 and C than in the remaining five stations whose grain sizes were analyzed. Although Station C constitutes a forereef envirorunent, it is located on the inner line of reefs and thus lies in the lee of the outer reef line. Many researchers (Brasier, 1975a, 1975b, Marshall 1976; Steinker and Steinker, 1976 ; Martin, 1986) have found a greater abundance of individual foraminifera (both t o tal and living

PAGE 112

99 populations) and higher species diversities in sediment samples associated with vegetation or phytal (a habitat consisting of plant material or hard surfaces such as coral rubble) samples compared to bare sand habitats Seagrasses trap sediments and organic matter, as well as produce organic matter, which foraminifera can utilize as a food source Middle Shelf Province Greater proportions of robust species such as Quinqueloculina lamarckiana, Peneroplis protea, Archaias angulatus, and Discorbis rosea from both backreef and forereef environments within the middle shelf province is the result of exposure to increased wave and current action in this area Brasier (1971) discovered milioline tests .in coarser substrates in exposed areas in Barbuda to be thick and often ornamented Triffleman et al. (1991) found the foraminiferal assemblage of Seranilla Bank on the Nicaraguan Rise to be characterized primarily by Discorbis rosea, and also by Archaias angulatus and Asterigerina carinata. These larger taxa can survive the windand wave-driven currents that control this bank top Archaias angulatus, Peneroplis proteus, Discorbis rosea, and Amphistegina gibbosa were the most common species collected from sands of the outer reef at Looe Key, Florida (Steinker et al., 1977). Ripple marks were observed in the sampled area indicating continued water movement in the region. In addition, higher turbulence was also responsible for the large number of

PAGE 113

100 abraded and broken tests collected particularly P protea, Archaias angulatus, and D. rosea Marshall (1976) and Brasier (1975b) also noted the common occurrence of abraded and rounded tests, of these larger foraminifera in higher energy environments. Tests of Rotorbinella (Discorbis rosea), that had lost their characteristic color from transport across Pedro Bank, were also observed by Brasier (1975b). Increased wave and current energy also contributed to the higher percentages of the larger grain size classes (1 and 2 mm) when compared to stations from the inner shelf province, particularly at Station I, where sediments were dominated by coarse sands The mud-sized fractions contributed less than 16% to the sediments at these stations. Med i um to fine-grained sands (comprised primarily of benthic foraminifera) were common within the interior of the bank and on the central and west margins of Seranilla Bank which is strongly influenced by Caribbean Current and the trade winds (Triffleman et al. 1992) Transitional Area The patch reef at Station H is unique in that it is the only site that lies between the outer reef line and the shelf margin Collections were made in the backreef area and therefore exhibit trends that are intermediate between the middle shelf characterized by a mix of porcellaneous and hyaline taxa and the Amphisteginadominated shelf edge

PAGE 114

101 Shelf Edge The predominance of the rotaliine fauna by Amphistegina gibbosa in both rubble and sediment samples from the shelf edge at 65 to 100 ft depths is striking. Many studies have documented the presence of Amphistegina as indicative of forereef or outer reef (Brasier, 1975b; Steinker and Steinker, 1977), reef or bank margin (Cebulski, 1969; Todd and Low, 1971), and slope (Martin and Liddell 1989), or reef flat (Seiglie, 1971a) habitats It is accepted that A. gibbosa flourish in open ocean regimes indicative of more oligotrophic conditions The preponderance of live specimens in rubble samples strengthens the assertion that this species is diagnostic of this type of environment. Martin and Liddell (1989) contend that large Amphistegina are abundant in slope and deep forereef foraminiferal sediment assemblages off Jamaica in part because of their resistance to dissolution. The increased organic carbon content associated with the fine-grained sediments of this habitat more readily dissolve the smaller tests of the species, leaving the larger individuals to dominate This does not seem to be the case, at least at the depth we sampled at Station M. Although fineand medium-sized sands characterized the sediments, organic carbon values were the lowest of all stations The live assemblage of Amphistegina is probably utilizing the epiphytic bacterial and microalgal growth on the coral rubble it occupies. The relative high abundance of thinner-walled miliolines is not unusual for this environment. The effects of wind-driven waves and currents are dampened at the

PAGE 115

sampled depths allowing epiphytic organisms to settle on the abundance of coral rubble present at this site. Biocoenoses 102 The living component of foraminiferal assemblages has not been as well studied as total populations. This is due to the difficulty of many techniques to adequately sample the true living foraminiferal population (see also Le Calvez and Cesana, 1972; Martin and Steinker, 1973; Walker et al., 1974; Bernhard, 1988). Ideally, each sample should be examined under a microscope to determine protoplasm color prior to fixing. However. this is time-consuming and tedious, particularly when numerous samples are collected during short, sampling-intensive trips to isolated field locales. Although a common technique, Rose bengal in formalin has been shown to stain non-living protoplasm and tends to inconsistently color actual living tissue There is also the possibility that living material, i e., bacteria, diatoms, and microalgae, living on dead foraminiferal tests stain red and are misinterpreted for live foraminifera. Care was taken to reduce bias of the technique by counting as alive only those with distinct colored plugs of protoplasm. Additionally, living larger foraminifera (i.e., Amphistegina gibbosa and Peneroplis protea) were picked on the basis of their distinctive symbiont color.

representation of the actual living assemblage due to the pitfalls of the staining technique However, it was the technique most conducive to the logistics of the sampling regime. 103 The low frequency of living Soritaceans Archaias angulatus and Peneroplis spp particularly in backreef environments, is striking Although these taxa were consistently found alive at four forereef sites (Stations A, E, I, and J), their contributions were minor compared to other living taxa collected at these sites These findings contrast with those of numerous researchers who have worked in subtropical and tropical environments and who maintain that A angulatus is a predominant contributor to living foraminiferal assemblages in shallow-shelf habitats, particularly in macroalgal and seagrass-dominated environments [e.g., Todd and Low (1971) in the Bahama Banks, Steinker and Steinker (1976) in Jewfish Cay in the Bahamas, Hallock et al. (1986a) in Key Largo, and Martin (1986) in the northern Florida Keys] Martin and Liddell ( 1989) found Archaias a dominant component of the backreef assemblages of samples from two transects in Discovery Bay, Jamaica but, they also occurred in moderate abundances in samples along the forereef terrace down to depths of 15 m. Smaller, thinner-walled miliolines including Triloculina bermudezi and Miliolinella circularis were more prominent constituents of the living rubble assemblages, particularly at Stations C and D These sites, within the inner shelf province, are sheltered by the outer line of reefs. Consequently foraminifera with more fragile tests predominate.

104 Rosalinids and, to a lesser extent planorbulinids were well-represented in the living assemblage of the rubble samples. They occurred most prominently within the higher-energy middle shelf province. Representatives of both groups are encrusting, attaching firmly to a substrate which is advantageous in this habitat. Planorbulinids are flat and conform to the shape of whatever substrate they occupy (representatives collected in some samples were growing around cylindrical objects) Some rosalinids are also flat while others are small and do not protrude far from the surface of the substrate they inhabit. Martin (1986) documented an increase in living Rosa/ina bahamaensis and Planorbulina acervalis and a concomitant decline in live Archaias angulatus proceeding from a back-reef environment offshore He maintained that with their distinctive test morphologies, combined with their pseudopodia, rosalinids and planorbulinids are better able to withstand environments with higher current and wave energies than the larger A. angulatus. Although Martin examined Thalassia testudinum blades, the same argument could be made for rubble pieces providing an important habitat for living foraminifera. The various naturally occurring crevices and the holes created by boring organisms that are found on a typical piece of coral rubble, as well as epiphytic bacterial and microalgal growth, create an environment protected from currents and waves, as well as from predators (Hallock, 1984) Much of the rubble we collected was heavily bored and Acropora cervicornis a branching scleractinian coral with knobs along its surface was prevalent. This three dimensional habitat provides a variety of niches for foraminifera to colonize with an associated suite of available organic matter.

105 Diversity and Evenness The relative high diversity and associated evenness values of rubble samples characterize a speciose assemblage that is dominated by many taxa. Although values for most samples were similar, regardless of location, a few patterns were evident. The three lowest values were obtained from Station G (inshore) and Station M at the shelf edge. This might be explained by the predominance of Strebloides advenus and Amphistegina gibbosa, respectively, at these locations. Each species accounted for approximately 30% of each sample assemblage Conversely, speciose forereef habitats such as Stations A, E, and H displayed correspondingly higher species diversity and evenness values. In sediment samples, PR-53 (Station E), PR-67 (Station F), and PR-81 (Station G) had the lowest diversity and evenness values due to very high abundances of Archaias angulatus and Discorbis rosea (PR-53 and PR67) and Strebloides advenus (PR-81). Additionally, samples from Station M, dominated by Amphistegina gibbosa, exhibited relatively low diversity and evenness indices. Again, forereef stations, in this case samples from H and I, consistently displayed high diversity and evenness values. Martin and Liddell (1989) sampled two transects off Discovery Bay, Jamaica and found comparable trends. They obtained relatively low diversity (-2.3 3) values in the backreef environments of two transects off Discovery Bay, Jamaica. Indices of forereef terrace samples fluctuated corresponding to Amphistegina gibbosa abundances, and were at times less than backreef values. They also found increased values in forereef habitats with the

PAGE 119

106 highest value found in the upper deep forereef at 75 m. Sen Gupta and Schafer (1973) reported diversity indices between 2 5 and 3.5. Individual samples from the two St. Lucia bays they studied also had lower number of species than the present study which explains the lower diversity values. CONCLUSIONS The baseline data collected in this study will be useful for future research in this area. The sites can be resampled years from now to determine any changes in the foraminiferal assemblages, sediment grain size, and sediment organic carbon values If the reefs at La Parguera are dominated by a sponge-algal community, then patterns of faunal distribution related to grain size and TOC val ues might help to identify the extent of nutrification. Results of the present s tudy prompted the following conclusions. 1)The highly diverse foraminiferal assemblage off La Parguera was similar in species composition to other areas in the Caribbean/ Antilles province. 2) In spite of its species richness and general homogeneity, some distributional patterns were evident. The station from the inshore seagrass bed was dominated by characteristic backreef or "lagoonal" species including Strebloides advenus, elphidiids, and bolivinids. The protected inner shelf province was characterized by the presence of smaller, thin-walled miliolines. The middle shelf region contained a suite of larger more robust species able to withstand the increased

PAGE 120

energy of the environment. Finally, the shelf edge fauna was distinguished by Amphistegina gibbosa which is typically found in more oligotrophic habitats. 3) Only the rubble samples supported an appreciable living foraminiferal population. A possible explanation for this is the increased organic matter and protection provided by phytal substrates compared to bare sand 4) Grain size and sediment TOC were associated with particular species groups within each shelf province Stations whose sediments were dominated by smaller grain sizes had higher values of total organic carbon and included higher numbers of smaller, thin-walled miliolines, and conversely, stations with higher proportions of larger grain sizes typically had lower TOC values and contained greater percentages of more robust taxa 107

APPENDIX 1 Descriptions of the stations sampled at La Parguera Information concerning sediment and rubble samples, prevailing meteorological conditions during sampling, physical and chemical parameters acquired, and observations of the habitats at the time of sampling is included. Salinity was measured in the field with a refractometer and values were subsequently calculated by calibrating with a second refractometer. It should be noted that values obtained seem a bit high when compared with previously recorded values from this area. Water temperature and dissolved oxygen were determined with a YSI meter at 2 m depth. The designation nd (no data) is used in instances when the information could not be obtained. Only the samples processed and used in analyses are included here.

A sparse Halophila meadow covered the sandy area extending seaward from the reef base. The reef gave way to sand fairly abruptly, but there were a few stony coral outliers < 1 -2 m high. These were probably former coral heads now populated by plate corals (25 em diameter or less), fllamentous algae, and sponges. There was little to no organic and fine sediment detritus on the hard substrate. The sand had only a thin algal/bacterial mat, probably less than 1h em. The sediments appeared anoxic or at least previously anoxic within 1 em of the surface The sediment did not look anoxic in situ, but the core showed gray sediment within about 1 em of the surface. Halophila rhizomes, though not abundant, somewhat stabilized the generally coarse sand. Rubble was predominantly shell pieces or algal overgrown Acropora or Porites. Rubble did not appear to be accretionary. Acropora cervicornis, Colpophyllia natans, Diploria sp Montastraea cavernosa, and Porites sp. were among the living stony corals. Gorgonians included Eunicea spp., Gorgonia ventalina, Muricea spp., Plexaura jlexuosa, Pseudoplexaura sp. and Pseudopterogorgia spp. Samples obtained for total organic carbon (fOC) determinations and grain size analysis were taken from coarse sand in the Halophila meadow below the reef break.

The sand was moderately coarse, stabilized in the upper 1 -2 em by an algal/bacterial film. Anoxia was detected within approximately 1 em of the surface. Moderate densities of Ha/ophila and a fleshy brown alga stabilized the open sand. The open sand topography was marked by large mounds, possibly Callianassa burrows. The sediment at the reef-sand break was much finer, than that of the forereef, and the organic stabilization was 2-3 em over a coarse undersand. The minicore was hard to use in this sediment (incipient lithification?). A drape of lime mud and organic gel was evident on hard substratum. Large gorgonians including Gorgonia ventalina and P/exaura spp. were common on the hard substrate. Small stony coral patches were evident, most corals were approximately 25 em in diameter, many were overgrown especially on the upper surface. Corals encrusted on vertical and underhang surfaces seemed more common. Sediment was anoxic 1 em or less below the sediment-water interface. At 3 m depth, the sediment was gooey" and anoxic immediately below the surface The sediment samples for TOC determination were obtained from the fine organic layer (drape) at the base of the reef (i.e., reef sediment interface).

Although the trade wind chop and small swells greatly influenced work at the surface, the reef itself seemed amazingly uninfluenced, at least with respect to sediment texture. 124 The sediment at the sediment/reef break was an incredibly fine gel, almost soupy. One could sink several centimeters before hitting firmer sediment. Anoxia was detected within approximately 1 em of the surface. Montastraea annularis, M. cavernosa, and Porites astreoides seemed fairly common. Gorgonians were represented by Gorgonia ventalina, Plexaura jlexuo s a and Pseudopterogorgia spp Iridescent sponges were seen and Acropora c ervicornis first occurred at about 9 m, but was not dominant. Millepora alcicornis (fir e c oral ) was first noticed at 6 m. Sponges and fllamentous algae were common. Althou g h the rubble seemed accretionary at 1.5 m it was well-covered by a thin, filamentous veneer of algae.

The sediment at the base of the reef was covered by an 8-cm thick gel which was anoxic below a few millimeters. Sample PR 72 was collected from the gel The detritus in the water resembled a light snowfall. Strings of sediment in an organic gel draped the hard substrate of filamentous algae and assorted sponges. Fish were abundant The "reef' consisted of a line of hard substrate between -14 and 9 m. Above that was what may have once been an Acropora cervicornis bed for rubble was abundant and covered by a very thick growth of small, brown macroalgae. This habitat extended fairly steeply from 9 -4.5 m. Scattered patches of living stony coral occurred at approximately 3-4.5 m and consisted most frequently of Montastraea annularis and Porites astreoides. Gorgonia ventalina and Pseudopterogorgia spp. were common gorgonians.

The most living stony coral was observed at this site. Large, living heads of Montastraea annularis and Colpophyllia natans occurred. Sand below the break was stabilized by sponges, Caulerpa, Halophila, and gorgonians. The impressive gorgonian fauna was represented by Briareum asbestinum, Eunicea spp., Gorgonia ventalina, Ple.xaura jle.xuosa, Ple.xaurella sp and Pseudopterogorgia spp. There was substantial Acropora rubble but it was not accretionary; it was covered by moderate algal growth. Generally this seemed to be a relatively healthy reef There was no visible organic geUsediment drape on the hard corals The stony coral cover and diversity remained impressive up the reef face M. cavemosa, Mycetophyllia sp., Porites astreoides and P. porites occurred. Millepora alcicomis became abundant at about 6 m. A few large colonies of Acropora palmata occurred in very shallow water. Anoxia was not detected in situ at 15 m.

Anoxia was detected within 1 em of the sediment surface. The sediment was stabilized by a thick microalgal/bacterial film, not by macroalgae or Halophila as at previous sites. On the hard substrate, gorgonians were the visually dominant forms with Gorgonia ventalina common. Sponges and tunicates were also present with only occasional, small stony corals including Porites astreoides. Gorgonians continued to dominate up to -3 m, while Millepora alcicomis was common at the shallower depths Substantial surge was noticed at less than 4 5 m Rubble and sediment samples were collected by snorkeler at 1 -2 m in the shallow backreef.

Hard substrate was along a ridge that extended from 14 m on the windward (east) side to 10 m or possibly as shallow as 7.5 m then down the leeward (west) side to 15 m There were numerous gorgonians on the windward sediment/reef break (14 m). Gorgonians included Briareum asbestinum, Gorgonia ventalina, Muriceopsis sp., Plexaura jlexuosa, Plexaurella sp., Pseudoplexaura sp., and Pseudopterogorgia spp. There was much coral rubble, probably Acropora, scattered over the sediment, especially windward. The rubble was overgrown by filamentous algae, though not to the thickness observed at Station D. There were occasional living stony corals in the hard substrate, including Porites astreoides and Agaricia agaricites, but far fewer than the lush stony coral growth seen at Turrumote (Station E) Bottom sediments were not suspended except by diver disturbance. The sand was coarse and anoxia was not detected. Halophila was common in the sand. Halimeda, Acetabularia, and serpulids were also observed at this site.

There was no rubble at the bottom. The surge was substantial. The sediment/reef break occurred at 10m. The mud was very fine and was anoxic within less than 1 em of the sediment-water interface There was no rubble at this depth The hard-substrate fauna consisted mostly of filamentous algae, sponges, and gorgonians. The gorgonian fauna included Gorgonia ventalina, Muricea spp. Muriceopsis sp., Plexaura homomalla, Pseudoplexaura sp., and Pseudopterogorgia spp. There were a few living stony corals including Acropora cervicornis, Millepora alcicomis, Porites astreoides, and Siderastrea siderea. Lime mud organic gel draped the hard substrate and rubble was scarce, however we did finally fmd some rubble at 6 m. The abundance of coral increased upslope. Acropora palmaJa was common at less than 3.5 m, though the heads were rather small and fairly isolated.

The small reef came up to about 3 m depth, and was covered by gorgonians and assorted stony corals. Gorgonia ventalina and Pseudopterogorgia spp. were abundant gorgonians. Colpophyllia natans, Montastraea annularis, M cavernosa, and Diploria labyrinthiformis were among the stony corals. In the shallowest areas live Acropora palmata was present, covering approximately 20% of the area. live M. annularis, Porites astreoides, and P. porites accounted for approximately 5% each of the area, and sand covered about 45% of the area sampled The habitat at 4.5 m was dominated by gorgonians and sand. Large coral heads (50%), gorgonians, sand, and dead rubble were the most prolific at Laurel reef at 4.5 m. Sand accounted for 70% of the area on the reef flat. Sediment from the west side of the patch reef was anoxic within a few centimeters of the surface. There was much rubble strewn about both the patch reef and the Laurel reef Young, small A. cervicornis were recruiting, especially at the base of Laurel. Finding a sampling site at the sediment-reef interface was difficult because Millepora alcicornis and small colonies of A. cervicornis were abundant in the sand. The striking thing was the abundance of stony corals at 4.5 m or less.

The open shelf/shelf slope break was populated by abundant hard corals including Colpophyllia natans, Montastraea annularis, M. cavenwsa, and Diploria sp. The break configuration was that of deep spur and groove The spurs were broad buttresses and the grooves were very narrow barely large enough to sample in. Samples at 30 m came from a groove which was transporting a limited amount of sediment downslope. Anoxia in the sediment was not detected Gorgonians including Gorgonia ventalina, Plexaura jlexuosa, and Pseudopterogorgia spp encrusting hard corals (Agaricia sp., M. annularis, and Porites astreoides) and sparse sand made up the substrate cover. The second set of samples was taken from a small sandy patch beh ind the shelf/slope break at about 18 m. Numerous live Amphistegina gibbosa were collected
